JOSEPH RETALLACK, OF DENVER, COLORADO.

TIME TEMPERING-MACHINE.

To all whom it may concern.

Be it known that I, JOSEPH Rn'rALLAoK, a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented a new and useful Time Tempering-Machine, of which the following is a specification.

This invention relates to improvements in time tempering machines the primary object of the invention being the provision of a machine whereby the cutting or entering end of bits may be properly tempered from the extreme cutting point thereof to a predetermined distance beyond the same, the said machine being provided with means for receiving and holding the said head in an upright position, and delivering it to a tempering liquid gradually increasing the submergence of the cutting end of the bit, until the same is tempered for the proper length of time, at which time the bit is released and permitted to fall by gravity exteriorly of the tempering fluid.

A further object of this invention, is the provision of a machine of this character provided with a vat or tank containing the tempering fluid, and an endless belt conveyer mounted inclinedly within the body of tempering fluid whereby the ends of the bits are so disposed and travel with said endless belt to be presented at a gradually increased depth within the tempering fluid, a simultaneously operated endless clamping device being so mounted and disposed with regard to the submerging endless belt, that the bits are retained in an upright position, to insure the even submergence within the tempering fluid, and to also permit the upper end of the bit to be released at the proper time, when the cutting ends of the bits have been properly tempered and have traveled a sufficient or desired distance within the tempering fluid within the tank.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood Specification of Letters Patent.

tempering apparatus in operable relation therewith. Fig. 2 is a top plan view of the vat, with the lower bit receiving and carrying endless belt with its operating mechanism. Fi 3 is a detail view of the clamp showing the position a bit assumes during the tempering operation. Fig. 4; is a similar view of the clamp releasing mechanism to permit the bit to fall of its own weight exteriorly of the tempering tank.

Referring to the drawings, the numeral 1 designates the tempering fluid retaining vat or tank, which is preferably of rectangular shape with an open end, the full length thereof, and has mounted centrally thereof to one side thereof thetubular column 2, and the upright arm or bracket 3 at the discharge end thereof.

J ournaled transversely at the entrance end of the vat or tank, is a shaft 4, while journaled in the bracket 31 near the other end of the vat or tank is a shaft 5, the same projecting into the vat and parallel with the shaft 4, but at a lower level within the tank, so that the respective sprocket wheels 6 and 7, which carry the endless conveying belt 8 will cause the said conveying belt to have its upper lead inclined from the entrance to the exit end of the tank or reservoir, the level of the tempering liquid within the vat 1 being approximately upon the dotted lines in Fig. 1, whereby the entrance end of the conveyor belt 8 is slightly above the level while the exit end thereof will be below the level.

Mounted at equidistances and carried by the endless belt 8, are the bit receiving receptacles or pans 9, of such a shape as to receive the lower end of the bit A, and as the said belt 8 moves from the entrance to the exit end of the tank, the said bit A being held in an upright position, has its cutting or lower end mounted in one of the pans or receptacles 9 submerged within the tank, the depth of the submergence being gradual from the entrance end to the exit end of the Y 14, whereby motion is transmitted to the elements of the machine.

Journaled within the bracket 16 and having the lower pinion 16 thereof meshing with the pinion 10, is the main drive and vertical shaft 17, while the parallel arranged guiding shaft 18 is journaled in the upper end of the bracket or support 3. Both of these shafts 17 and 18 have their upper ends j ournaled at 19 in the bearings in the outer ends of the support 19 supported at the upper end of the column 2.

Surrounding the column or cylindrical support 2, is a collar 20, which has oppositely extending therefrom the arms or supports 21, provided with the longitudinally disposed guide plate 22, and mounted upon so as to rotate with the respective shafts 17 and 18 but permitted a sliding movement thereon, are the sprockets 23 and 24, which operate the endless chain 25, carrying thereon the bit receiving carriers or clamps 26, which are so disposed as to project beyond the guide strip 22, so that the bit A when having its cutting end resting within one of the receptacles or pans 9 of the belt 8, has its upper end received within one of the clamps 26 and held in a vertical position and prevented from inward movement by means of the guide 22, as the said belt or conveyers 8 and 25, respectively, pass from the entrance end to the exit end of the tank or reservoir 1. The upper end of the bit being relieved from the clamp 26 as the pan 9 carrying the lower end thereof passes above and starts around the sprocket wheel 7 thus causing the upper end of the bit A to tilt or incline so that it will assume the position of dotted lines in Fig. l, and by reason of the greater length thereof projecting ex teriorly of the tank, said bit will tilt and fall beyond and without the tank and thereby be automatically released and delivered after having its cutting or lower end properly tempered.

In order to accommodate this machine to various length bits, the supporting arms 21 carried by the collar 20, have their outer ends slidably mounted upon the respective shafts l7 and 18 and by means of the flexible cables or ropes 27 which pass over the oppositely disposed guide pulleys 28 at the top of the column or tubular support 2, and are position with relation to the water level in the tank 1, and therefore by reason of the fact that the endless belt inclines from the entrance to the exit end of the tank, that the water or tempering fluid level within 1 the tank or reservoir, 1, will cause the cutting end of the bit when in such perpendicular position with relation to the water level in the tank, to be gradually submerged at a varying depth from the entrance to the exit end of the tank, thus giving the lower cutting end a longer tempering and gradually decreasing the tempering operation from the lower end to the point according to the depth that the fluid has at the exit end of the tank.

In order to regulate the depth to which it is desired to temper the bit, the bracket 31 is adjustably mounted within the tank 1, so that the crank 32 may be operated to raise or lower the shaft 5 and its sprocket 7, thereby using a greater or less incline of the belt 8 and getting the proper depth or submersion at the exit end of the tank or reservoir.

As clearly shown in Fig. 3, the clamps 26 each comprise the attaching plates 33, connected to its proper link of the chain 25, and the plate 3 f having the arm 35 and the stationary jaw 36. Connected at one end to the arm 35 is a spring 37, attached to the lever 38 of the pivoted ja 39, the spring 37 normally exerting a tension to hold the jaw 39, and coact with the stationary jaw 36 to properly support the bit A during its travel. As the clamp 26, is moved opposite the discharge end, the curved guide 40, is engaged by the lever 38, causing the j aw 39 to assume the position as shown in dotted lines Fig. 3, the guide 4E1, being disposed to engage the upper freed end of the bit A and not permit it to fall until the clamp 26 has rounded the sprocket 24 at which time the terminal 12 will permit the upper end of the bit A to fall outwardly and be discharged from the machine exteriorly of the tank.

From the foregoing description it is evident that the belts 8 and 26 may be regulated to travel at any desired speed, and that the tank 1 may be decreased or diminished in length, to accommodate itself to tempering bits to the desired hardness, and that by reason of the adjustability of the belt 25, various lengths of bits may be accommodated and always be retained in a vertical and perpendicular position, so that the bit end or cutting end of the respective bits, will be properly submerged in the tempering fluid within the tank, so that said cut- 1 ting end may be tempered longer and to a harder degree than the remaining portion of the bit, the portion therefore being gradually tempered from the hardest to the toughest tempering desired. By this construction it is also evident that the bits although placed in position manually, are delivered automatically from the machine at the end of the tempering operation from where they may be gathered when desired.
